Compression and impact tests were used to evaluate the deformation and breakage behaviour of spherical granules. e best performance was obtained by zeolite granular containing 5 wt.% bentonite and 5 wt.% kaolinite with mechanical strength and satisfactory water resistance. e synthesis of pelletized zeolite from by-products derived from coal combustion provides not only environmental and economic benets, but also contributes to achieving the principles of sustainable development.13-22openAccesszeolitesfly ashpelletsmechanical propertiesArtigo de periódico2310.31258/Jamt.3.2.13-230000-0003-1618-0264https://orcid.org/0000-0003-1618-0264Sem PercentilSem Percentil CiteScore
